Different UPS shipping options based on Zip/State/?

I've searched the threads, but haven't found a solution to this (seemingly simple) problem:

We want to offer UPS Ground shipping as an option only for California (in addition to Overnight & 2nd Day). All other states/zips should only have Overnight & 2nd Day as options.

Yes, we have a UPS account and can pull the Overnight & 2nd Day costs, just can't seem to get Ground to come up for CA only.

Any help would be much appreciated!

Thanks,
Jeff

You could customize the ups.php shipping module with something like:

      for ($i=0; $i<$qsize; $i++) {
        list($type, $cost) = each($upsQuote[$i]);
        // BOF: UPS USPS
        if ($type=='STD') {
          if ($std_rcd) continue;
          else $std_rcd = true;
        }
        if (!in_array($type, $allowed_methods)) continue;
        // EOF: UPS USPS

        // Show UPS Ground only for California
        if (($order->delivery['country']['id'] == 223 && $order->delivery['zone_id'] == 12)) {
          $show_ground= true;
        } else {
          $show_ground= false;
        }
      
        if ($type == 'GND' && !$show_ground) {
          // show nothing
        } else {
          $methods[] = array('id' => $type,
                             'title' => $this->types[$type],
                             'cost' => (($cost + MODULE_SHIPPING_UPS_HANDLING) * $shipping_num_boxes) + $inspection_fee);
        }
      }

Brilliant! I still need to run a few tests, but that looks to be the ticket.

Many thanks!
